LIQUID-FUEL BURNER.

Application filed November To all whomz't may concern Be it known that I, Josnrn WV. FLYNN, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsyl t vania, have invented certain new and useful Improvements in Liquid-Fuel Burners; andL I do hereby declare the followinguto be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

This invention relates to liquid fuel burners, and consists in the improvements therein hereinafter described and pointed out, and which are illustrated in the accompanying drawings inwhich:

Figure 1 is a top plan View of a liquid fuel burner embodying my invention.

Figure 2 is a transverse central section of the same on the line 2-2 in Fig. 1.

Figure 3 is a plan view of the base plate.

Figure & is a transverse section of one of the air heating tubes, on the line 4.- i in Fig. 2.

Figure 5 is a plan view of the cap of my burner, removed, and turned bottom side up.

Figure 6 is a front elevation of the air heating tube shown in Fig. 4 before the filling material has been applied.

In these drawings A indicates the base plate, which is providedwith a downwardly thereof, said base plate is also provided with openings A therethrough. The plate Ais also provided with a raised rib or flange 0. around said openings A said rib a extending along the perimeter of said base plate A between said openings A so that the upper surface of said plate will be saucer-shaped.

extending flange A along the perimeter Serial Ira-743,401.

Uponthe ribs a around the openings A i place metallic tubes E, see Figs. 2, 4i and 6, the walls of. which have openings 6 therethrough. Adjacent to the margins of the outside of said tubes E are integral raised ribs 0 which enclose the depressed portion 6 of the face of said tubes.

These depressed portions, 6 oft-he elite rior of the tubes E are filled with a layer of heat absorbing material F, which is put in place in the form of plaster, andportions thereof enter the openings, 6, in the wall of the tube, as shown in Figs. 2 and 4:, after which the tube E is baked until it is dry.

Upon the upper ends of the tubes E I place a hollow cap G, which has openings G see Fig. 5, which are adapted to coincidewith the upper ends of the tubes E. The under waii of the hollow cap G is provided with an opening G which, when the cap is in place, as shown in Figs. 1 and 2, will be immediately above the conical generator D.

The base plate A, within the openings A is provided'with flange shoulders a which extend into the tubes E, and are adapted to keep said tubes in place upon the ribs, a, of the base plate, and the cap G is provided with flange lips g which are adapted to overlap the air heating tubes E, and thereby maintain the openings G in the under side of the cap G in coincidence with said tubes.

In operation, fuel oil is supplied to the jet tube B through the pipe C, from which it flows down over the outside surface of'the stepped, conical generator D where it is ignited in any suitable manner. 7

As the generator D becomes heated the fuel boils in the trough-like grooves around the outer surface of said generator, thereby generating a combustible gas, and as the draft of the chimney (not shown) draws air upwardly through the openings A in the base plate A, and thence through the tubes E and cap G, it flows downwardly through the opening G in the under surface of the cap G and impinges against the generator D, which causes the flame to flow radially from the generator D so as to impinge against the air heating tubes E thereby heating said tubes and said cap, so that the air, while flowing'therethrough becomes highly heated, until the entire structure becomes highly heated. The liquid fuel in the hollow cone also becomes heated so that as it flows down over the generator D, does not cool the same,

but instantly commences to boil upon the outer surface thereot thereby generating a combustible gas.

The tubes E being covered with a coating of refractory material F become highly heated and sometimes become White hot, but owing to the coating F do not become oxidized or burned up, as said coating of refractory material protects the metal Walls of said tubes from the tire.

Having thus fully shown and described my invention so as to enable others to utilize the same, What I ciaim as new and desire to secure by Letters Patent is:

In an apparatus of the class described a base having a chamber in the intermediate portion thereof to receive fluid fuel, a conical generator plate suspended upon and in spaced relation to the upper Wall of said chamber, a fluid fuel jet extending through the apex of said generator plate and communicating With said chamber whereby fluid fuel is supplied to said generator plate, and a tubular air conductor adapted to direct a current of air downwardly upon the apex of said conical generator plate.

In testimony whereof I affix my signature.

JOSEPH W. FLYNN.
